HARROW.

Application filed August 25,193.. Serial No. 786,554.

To all whom it may concern:

Be it known that I, HENRY L. EAvEs, a citizen of the; United States,residing at Mangum, in the county of Greer andState of Oklahoma, haveinvented certain new and useful Improvements in Harrows, of which thefollowing is a specification, ref erence being had to the accompanyingdrawlugs.

1 This invention relates to harrows and it more partlcularly relates toan improved sweeparrow.

One of the objects of the invention is to provide a swee -harrow of thischaracter which is especia ly designed to be attached to the foot piecesof a cultivator, for. the purpose of stirring the soil or breaking thecrust thereof which forms after it has rained and the sun has baked thesoil.

Another object of the invention is to provide a harrow of this characterwhich is designed to be operated in contiguity with the young and tenderplants without detriment thereto in the event that the harrow moves 26into contact therewith.

Another object is to provide a harrow of this character which is simpleof construction, comparatively inexpensive, strong, durable andthoroughly practical and eflicient.

In the accompanying drawings which supplement this specification, Figurel is a top plan View of my improved sweep harrow. Fig. 2 is a frontelevation thereof, the lower portion of the teeth being broken away, andFig. 3 is a side elevation.

In these drawings in which similar reference characters correspond withsimilar parts throughout the several views, the body 5 of the harrow ispreferably formed from a single sheet of metal, and may be easilystamped by ordinary methods and means. This body or frame is forked, themiddle fork or tang 6 being in alinement with the line of travel andwith a forward projection or tongue 7 which is gradually curved upward.The outside or lateral tangs 8 are gradually curved inward and convergein the direction of the forward end of the plate or frame. The tangs 8are each provided with apertures 9 through each of which extends thescrew threaded upper end of a harrow tooth 10, each said harrow toothbeing provided with a shoulder 11 which fits snugly against the lowersurface of the frame 5, while a nut 12 is provided on each tooth 10 forsecuring it on the frame. At

body is apertured for the reception of a harrow tooth 10, said tooth.being the same as the teeth 10 in all respects except that it issomewhat shorter, preferably about one-half of an inch. The supportingelement or tan 6 is provided with apertures 6, throug which bolts orother anchoring devices may be extended for securing the harrow on thefoot piece of a cultivator. This tang 6 is gradually curved upward andrearward, and

the curvature thereof may be made to conform to the configuration andposition of the cultivator foot piece to which it is to be attached. Theframes 5 are preferably formed of temperable steel so that the tang 6may be properly shaped for fitting any particular cultivator and maythereafter be tempered, so as to comprise a spring so that the harrowmay have limited movement over stumps, roots and stones, relative to thecultivator, without detriment to the harrow.

It will be seen that I have provided a de-c vice of this character whichis fully capable of attaining the desired objects, as specified in theforegoing, in a thoroughly practical and effective manner.

lVhile I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope of the appended claims.

WVhat I claim is 1. A sweep-harrow comprising a frame formed from asingle piece of sheet metal into the form of a fork having lateral tangsand an upturned tang between the lateral tangs, teeth carried by thelateral tangs, and a tooth carried by the frame forwardly of theupturned tang, said upturned tang being adapted to be secured to acultivator foot piece substantially as specified.

2. A sweep-barrow comprising a frame formed from a single piece of sheetmetal into the shape of a fork having lateral tangs and an upturned tangbetween the lateral tangs and an upturned extension in alinement withsaid upturned tang, and harrow teeth carried by the frame, said upturnedtang being adapted to be secured to a foot piece of a cultivator.

3. A sweep-harrow comprising a plate of metal having a forwardly andupwardly exthe conjunction of the elements 7 and 8, the

tendin tongue and having apertures therethroug harrow teeth secured inthe apertures, and a tang of temperable steel extending rearwardly andupwardly from the plate and being adapted to be secured to a cultivatorfoot piece.

4. A harrow frame comprising a single piece of sheet metal formed in theshape of a fork with lateral ta-ngs and an upwardly and rearwardlycurved tang between the lateral tangs, the lateral edges of said harroWframe being forwardly converging, and the front end thereof being formedwith a forwardly and upwardly extending tongue.

lntestimony whereof I hereunto afllx my signature in the presence of twowitnesses. HENRY L. EAVES. Witnesses:
